When Wez rips the door off the tanker you can see a crouched crew member next to Max. This has been disputed but it is there, watch underneath the steering wheel just after Wez starts shouting "Go! Go! Go!".
When Max opens the Semi's door, a dead body falls out. This body is actually the same "eye popping" dummy that was used at the end of Mad Max 1.
